The frontwall 22 has an opening for the sleeve 34, in which is slidably supportedthe lens barrel with the condenser lenses 36, 37. A U' shaped ventilatorduct 38 is formed with the front wall 22 and side walls 24. Openings 39in the front wall 22 and openings 40 in the side walls 24 coact withsaid duct.

rear wall 23, side-walls24 and roof 25.-

ported in the columns 53, 54 by means of the screws 58. A Ushapedbracket is carried on the rod 56 and a U shaped bracket 61 iscarried on the rod 57.

A supporting plate 63 with the openings 64, 65 and the supporting plate66 with the opening 67 are carried on the U shaped brackets 60 and 61.Separators 68 extend between the plates 63 and 66. A supporting bar 69is fastened to supporting plate 63 and has extending up therefrom theend stops 70. Springs 71 extend up from the supporting bar 69 and bearupon the glass guide plate 72. The latter has formed therewith theprojecting guide strips 73. An accompanying glass guide plate 75 withthe projecting guide strip 76 is supported in the annular frame 78, thelatter being secured to the supporting plate 63. A supporting guide 85and supporting brackets 86, 87 ex- -tend from the supporting plate 63and on An electric switch 43 with the handle 44 is supported on the baseplate 20. Wires 48,-

49 connect the switch 42 with the lamp socket 41. A coil 50 with twomain line wires for a source of electric current are connected to saidswitch 43.

A pair of tubular supporting columns 53, 54, extend from the plate 55,which latter is supported on the base plate 20. Supporting rods 56, 57are respectively adjustably'supwhich is slidably supported the filmslide bar 88.

A block 89 with the bifurcated end 90 is supported on the slide bar 88.It has pivoted therein the gripping finger 91, one end of which passesthrough 'the'opening 65 of the plate 63 and engages'the openings 92 inthe connecting strips 92 of the film 93.

A spring 94 has one end fastened to the block 89 and the--other- ..endbears on the gripping finger 91, to maintain the latter in properpositlon. Apin-95 extends from the bar 88. A bracket 98 extends from thebar 88 and has fastened thereto theoperating handle 99. Film guides 100and 101 extend from'the supporting plate 63. The film guide 101 has theopening 102 for the gripping finger 91.

The plate 66' has supported thereon the brackets 105, 106 which haverespectively journaled therein the rollers 107, 108 for the bands 114and 115. An annular frame 116 with the lug 117 having the opening 118 isfastened to one of the ends of each of said bands, and an annular frame119 is fas tened to the other ends of the bands. The opening 118 lockswith the pin 95.

On the ends of the supporting plates 63 and 66 are fastened the journalbrackets 121, 122 which have respectively journaled therein the guiderollers 123, 124. One of the brackets 121 has adjustably journaledthere- 'in the tension roller 125, by means of the threaded spindle 126and jam nut 127 Bifurcated journal brackets 128, 129 extend from thesupporting plate 66. A pin 133 is journaled in the bracket 128 and whichsupports the film receiving drum 134 having the clamping spring 135 andflanges 136. A clamping sleeve 138 having the disk 139 with the lockingpin 140 is fastened to the pin 133. The locking pin 140 looks with anopening in one of the flanges 136. A worm wheel is loosely carried onthe pin 133, and a pawl 146 is pinned to said wheel. A ratchet wheel 147is fastened to the pin 133, and a spring 148 carried on.

the worm wheel 145 bears against the pawl 146.

An auxiliary-bracket 149 extends from the bracket 128 and an auxiliarybracket 150 extends from the supporting plate 66. A worm shaft with theworm 156 is journaled in the brackets 149 and 150. The worm 156 mesheswith the worm wheel 145. An operating handle 158 extends from the wormshaft 155. A. pulley 160 is fastened to the pin 133. A pin 163 similarto 133 is journaled in the bracket 129. A feeding drum 164 with theclamping spring 165 and flanges 166'is carried on the pin 163. A splin'e167 extending from the pin 163 engages a notch in one of the flanges166. A handle 168 extends from one of the flanges 166. A pulley 170 isfastened to the pin 163 and a spring belt connects the pulleys 160 and170.

A sleeve with the tubular portions 178 and 179 extends from thesupporting plate 66. A tubular column 180 extends up from the plate 5.5,whichlatter is supported on the base plate 20. A supporting bar 181 withthe curved bracket 182 is adjustably supported in the column 180 bymeans of the screw 183.

A supporting sleeve 185 is slidably carried in the sleeve 179. A rack186 is carried on the sleeve 185. 'A bracket 187 is carried on thesleeve 179 and has journalm therein the spindle 188 carrying the pinion189, which latter meshes with the rack 186. A knurled head 190 iscarried on the spindle 188. A lens barrel is fastened in the supportingsleeve 185 and carries the objective lenses 196 and 197.

The film 93 has one end thereof fastened to the feeding drum 164 and iswound around the same. The said film is led from the said drum aroundthe rollers 124 and from t'hence between the guide plates 72 and 75. IThe film then is led between the film guides 100 and 101 and between therollers- 123 and the roller 125 and from thence to the receiving drum134.

To use the machine as a stereopticon the operator pulls the handle 99and thereby theslide bar 88 is moved and the gripping finger 91engagesthe openings 92, one at a time and pulls the film 93 in the direction ofthe arrow A. The distance traveled by the film is controlled by thestroke of the finger 91 in the opening 65. \Vhen the said finger reachesthe end of its stroke a picture on the film is in proper position forthe axial center of the lenses of the machine. .The stroke of the slidebar 88 which carries the gripping finger 91 is a little longer than thelength of the opening 65. When the slide bar 88 is moved to propel thefilm it travels the full length of the opening 65 and upon its returnstroke, the finger 91 rides on the film 93 until it reaches the otherend of the opening, it then rides on the plate 63 during the completionof the return stroke of the slide bar 88. Upon starting another forwardstroke, the finger 91 again engages an opening in the film. Upon thereturn stroke of the slide 88 the finger 91 bears on the film 93 withonly very slight pressure. When the film 93 is to be moved continu ouslythe slide bar 88 is located so that the gripping finger 91 will bearupon the supporting plate 63, a little beyond the edge of theopening 65which in turn is adjacent to the axial center of the lenses of themachine. The annular frames 116 and-"119 at the same time will beaxially in line with each other and in line with axis ofthe lenses ofthe machine. When the film 93 leaves the drum 164 the latter turns onits axis and thereby rotation is given to the pulley 170. The latter, bymeans ofthe spring belt 175, transmits rotation to" the pulley 160. Thedrum 134 turns with the pulley 160 and the film is taken upfpnthe drum134. The pulley 160 is somewhat'smaller in diameter than the pulley 170-to 'maintain the requisite tensioniy -'on the film 93. The tension onthe film can be adjusted by locating the tension roller 125' indifferent positions, by means of the spindle 126 and the jam nut 127.With thefmovements of the slide bar 88 motion is transmitted to thebands 114.- and 115 through the lug 117 and pin 95. The pin 95 is alwayslooked in the opening of the lug 117. When a picture on the film 93starts to leave its position from the axial center of the lenses, theannular frames 1'16 and 119 move in opposite direc- 11 tions from theaxial center of the lenses to stop offthe light. The frames 116 and 119with their openings constitute a shutter for the machine. When thehandle 99 is moved in a direction opposite to the arrow A, the frames116, 119 again approach each other and are located in the axial centerof the the film. The slide bar 88 with its coacting elements remainstationary and the bands 114, 115 also remain stationary with theannular frames 116 and 119 in alinement with each other andwith theoptical axis of the l/JGIISGS of the apparatus.
